TDCOSMO XXVIII. The Hubble constant from the quadruply lensed quasar J1537 $-$ 3010 with precise time delays

A. Galan, A. G. Schweinfurth, S. H. Suyu +21

We present the first measurement of the Hubble constant ( $H_{0}$ ) from the quadruply-lensed quasar J1537 $-$ 3010, which has optically-measured time delays at $\sim 2%$ precision. We…

TDCOSMO. XXVII. JWST-based Lens Models and H $_{0}$ Measurement of WFI2033, HE0435, and PG1115

D. M. Williams, T. Treu, D. P. Johnson +13

Time-delay cosmography offers a one-step, distance-ladder-independent route to the Hubble-Lemaitre constant, H_0. We present new cosmography-grade lens models of three quadruply im…
